Titan part 805-216A is an inlet valve pusher assembly used to actuate the inlet valve in compatible airless sprayers. It helps control the flow of paint into the pumping chamber during the intake stroke. A worn or damaged pusher can cause priming issues, pressure loss, or erratic operation. Replacing this assembly restores proper valve timing and consistent spray performance.

The Titan 805-216A Inlet Valve Pusher Assembly is a critical component of the fluid pump section. It mechanically pushes the inlet valve open during the intake stroke, allowing paint to enter the pumping chamber. On compatible Impact and RentSpray airless sprayers, this assembly ensures proper valve timing, consistent pressure, and reliable priming.
A worn, bent, or broken pusher can lead to poor priming, loss of pressure, or erratic spray patterns. Replacing the inlet valve pusher restores the correct valve operation and helps maintain the sprayer’s performance.
| Valve actuation | Pushes the inlet valve open on the intake stroke to draw paint into the pump |
|---|---|
| Fluid flow control | Coordinates with the outlet valve to maintain consistent pressure |
| Priming support | Helps the pump establish suction for fast, reliable priming |
| Poor priming | Sprayer won’t prime or takes excessive time to build pressure |
|---|---|
| Loss of pressure | Pressure drops significantly during operation, especially under load |
| Erratic spray pattern | Intermittent or pulsing output due to inconsistent valve timing |
| Visible damage | Bent, broken, or excessively worn pusher observed during inspection |
Titan part 805-216A is compatible with the following Impact and RentSpray airless paint sprayers. Always verify with the parts diagram for your specific model and revision.
| Model | Component |

| Impact 640 | Inlet valve pusher assembly |
| Impact 640 I | Inlet valve pusher assembly |
| Impact 640 IA | Inlet valve pusher assembly |
| RentSpray 600 Impact | Inlet valve pusher assembly |
When addressing inlet valve issues, it’s often wise to inspect or replace adjacent components. These parts are commonly serviced alongside the pusher assembly to ensure complete repair.
Worn or contaminated seat/ball can cause backflow and pressure loss. Often replaced with the pusher.
Damaged o‑rings on the pusher or valve housing can lead to suction leaks and poor priming.
Scoring or wear on the piston rod can affect overall pump performance and should be inspected.
